Actually after looking a bit. not that i could afford one but was interested, i like the front of the BRZ better, even though its a tiny bit more expensive the subaru comes with some things stock that the FRS doesnt (HID's, NAV) and has better upfit options that the scion doesnt. and the net says due to different bushings in the rear of the subi they seem to understeer more, So FRS wins there...
All in all, i would drive both, but even with the drawback of "understeer" i would take the BRZ too lol
